Test System

Assembly

Installing a motherboard into the Carbide 678C is quite easy as the spacers are pre-installed and one comes with a guiding pin, which has the motherboard fall into place effortlessly. As you can see, there is plenty of space for long GPUs, and because of the wider body, a large CPU cooler is no issues either.


To add an SSD, simply push it into one of three slots until the plastic clip snaps into place. As today's SSD drives are a bit thinner than classic 2.5" spinning variants, there is a bit of wiggle room with most modern storage units, but that should cause no tangible issues.


To install a 3.5" drive, you will have to take out your screwdriver. The individual cages make adding such storage devices quite easy even in a full case. Once filled, simply slide the cage back into an for it intended opening and secure the three thumb screws to keep it in place.


Last but not least, installing the PSU is pretty straightforward as it simply slides in through the side before it is secured by traditional means through the rear of the case.


With everything in place, the Carbide 678C makes a very clean impression, especially because of the slightly angled part of the motherboard and well-placed grommet-covered holes—even if those openings are a bit compact. In the rear, the cable mess is nicely hidden and contained with plenty of space next to the PSU.

Finished Looks

Once you turn the system on, you will see two blue LEDs turn on as well. One is fairly large and in the front, while the other is embedded in the power button. I have placed the solid cover on top of the chassis for the sake of this review, but you should really consider moving the pre-installed fan if you want to close this opening off.


In the front, you can clearly see the intake fan spinning once powered up, and the insulated door does a good job at reducing the noise heard once closed, while the rear is pretty traditional and straightforward.
